Description

  The present invention relates to a technique for allowing a user to select a plurality of objects displayed three-dimensionally in a display image.

  In recent years, a technique called augmented reality has attracted attention. Augmented reality is a technology that adds information to a real-world video for display. For example, a real-world video and a virtual object are superimposed and displayed on a head-mounted display, or a video captured by a camera and additional information are superimposed and displayed on a display unit of a mobile terminal such as a mobile phone. Some are simple.

  When using a mobile terminal, functions such as GPS, electronic compass, and network connection are provided in advance, so that augmented reality can be realized without adding any special devices, and various augmented reality applications have recently appeared. ing.

  In these applications, the image captured by the camera and the accompanying information of the real-world object included in the image are displayed in a superimposed manner, but when the number of accompanying information is large, the screen is filled with only the accompanying information. There is a problem of being exhausted.

  Therefore, what is called a tag is used. This tag notifies the user that the accompanying information exists in the object behind, not the accompanying information itself. When the user selects a tag, accompanying information associated with the tag is notified to the user.

  However, individual tags are small and the number of tags is increasing. For this reason, when the user selects a tag, there are problems that the tags overlap each other and the tag behind cannot be selected, or the tags are densely packed and the desired tag cannot be easily selected. In particular, when an operation is performed using a touch panel type portable terminal, it is difficult to accurately select a desired tag from among dense tags because the screen is smaller than the size of a finger.

  Although the case where a tag is selected in augmented reality has been described above, the same problem occurs when a specific object is selected from many objects displayed three-dimensionally on a display image. For example, in a digital television, an infinite number of photographs are displayed three-dimensionally and a specific photograph may be selected by the user. In this case, the same problem occurs.

  Therefore, in order to allow the user to easily select an object hidden behind, objects arranged in the depth direction are sequentially highlighted by the user's button operation on the input device, and the desired object is highlighted. A technique is known in which, when displayed, a user performs a selection operation to select the object.

  Also known is a technique for selecting a plurality of three-dimensional objects that overlap in the depth direction from a position on the screen selected by a two-dimensional cursor, and selecting a desired object from the selected plurality of objects. (For example, Patent Document 1).

  However, in the first technique, it is necessary to press many buttons until the desired object is highlighted, and there is a problem that it takes time to select the desired object. Also, with the second technique, it is difficult to specify the position when the entire object is hidden, or it may be recognized as a position that is different from the position that you thought you specified when operating with the touch panel. There is a problem that an object at an incorrect position is selected.

  Hereinafter, an object selection device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of an object selection device according to an embodiment of the present invention. In the following description, the object selection device will be described by taking as an example a case where the object selection device is applied to a mobile phone including a touch panel such as a smartphone.

  The object selection device includes a sensor unit 11, an input / state change detection unit 12, a position acquisition unit 13, a direction acquisition unit 14, an object information database 15, a display information extraction unit 16, an input unit 17, a depth selection unit 18, a display determination. A unit 19, an object selection unit 20, a related information acquisition unit 21, a drawing unit 22, a graphics frame memory 23, a video input unit 24, a video frame memory 25, a composite display unit 26, a display 27, and a camera 28.

  In FIG. 1, each block of the input / state change detection unit 12 to the composite display unit 26 is realized by executing an object selection program for causing a computer to function as an object selection device. This object selection program may be stored in a computer-readable recording medium such as a DVD-ROM or CD-ROM and provided to the user, or may be provided to the user by being downloaded from a network-connected server. May be.

  The sensor unit 11 includes a GPS sensor 111, a direction sensor 112, and a touch panel 113. The GPS sensor 111 periodically acquires the navigation data transmitted from the GPS satellite, thereby periodically detecting the current position of the object selection device, and periodically acquiring position information indicating the detected current position. Here, the position information includes, for example, the latitude and longitude of the object selection device.

  The direction sensor 112 is configured by, for example, an electronic compass, periodically detects the current direction of the object selection device, and periodically acquires direction information indicating the detected direction. Here, as the direction information, for example, the direction of the object selection device with respect to the reference direction when a predetermined direction (for example, a northward direction) from the current position of the object selection device is set as the reference direction can be employed. As the direction of the object selection device, for example, an angle formed by the north direction and the vertical direction of the display screen of the display 27 can be adopted.

  The input / state change detection unit 12 detects an operation command input by the user or a state change of the object selection device. Specifically, the input / state change detection unit 12 determines that the user has input an operation command when the user touches the touch panel 113, and outputs an operation command input notification to the input unit 17.

  The state change includes, for example, a change in position and a change in direction of the object selection device. When the position information periodically output from the GPS sensor 111 changes, the input / state change detection unit 12 determines that the position of the object selection device has changed, and outputs a state change notification to the position acquisition unit 13.

  In addition, when the direction information periodically output from the direction sensor 112 changes, the input / state change detection unit 12 determines that the direction of the object selection device has changed, and notifies the direction acquisition unit 14 of a state change notification. To do.

  The position acquisition unit 13 acquires position information detected by the GPS sensor 111. Specifically, the position acquisition unit 13 acquires the position information detected by the GPS sensor 111 when the state change notification is output from the input / state change detection unit 12, and holds the acquired position information. The position information held by the position acquisition unit 13 is sequentially updated each time a user carrying the object selection device moves and new position information is detected by the GPS sensor 111.

  The direction acquisition unit 14 acquires direction information detected by the direction sensor 112. Specifically, the direction acquisition unit 14 acquires the direction information detected by the direction sensor 112 when the state change notification is output from the input / state change detection unit 12, and holds the acquired direction information. The direction information held by the direction acquisition unit 14 is sequentially updated each time the user carrying the object selection device changes the direction and changes the direction of the object selection device.

  The object information database 15 is a database that holds information on real objects. Here, the real object is various objects included in the video imaged by the camera 28 and displayed on the display 27, and is provided in a building such as a building, a store in the building, and the store, for example. This applies to specific objects. However, the present invention is not limited thereto, and various objects may be adopted depending on the abstraction level and granularity of the object, and may refer to the entire city.

  FIG. 2 is a schematic diagram showing an example of the data structure of the object information database 15. The object information database 15 is constituted by a relational database in which one record is assigned to one real object, and includes, for example, fields of latitude, longitude, and related information.

  That is, the object information database 15 stores latitude, longitude, and related information in association with each real object. Here, latitude and longitude indicate latitude and longitude, which are two-dimensional position information on the earth of each real object measured in advance. In the example of FIG. 2, since only latitude and longitude are included, each real object can be specified only at a two-dimensional position. Therefore, in addition to the latitude and longitude, the object information database 15 preferably includes a height indicating the height of each real object from the ground. Thereby, the position of each real object can be specified three-dimensionally.

  The related information is information for explaining the contents of the real object. For example, when the real object is a store, the related information corresponds to store information such as an address of the store, a telephone number, and a coupon. When the real object is a store, word-of-mouth information indicating the reputation of the store may be included as related information.

  Further, when the real object is a building, the date on which the building was built, the name of the architect, and the like may be adopted as related information. Moreover, when a real object is a building, you may include the store information of the store contained in the building, the link information to the store information, etc. Note that the object information database 15 may be stored in advance in the object selection device, or may be stored on a server connected via a network.

  Returning to FIG. 1, the display information extraction unit 16 generates the depth space shown in FIG. 3 from the latest position information acquired by the position acquisition unit 13 and the latest direction information acquired by the direction acquisition unit 14. The real object RO to be displayed is extracted by plotting the real object RO stored in the object information database 15 in the generated depth space.

  FIG. 3 is a diagram illustrating an example of a depth space generated by the display information extraction unit 16. As shown in FIG. 3, the depth space is a two-dimensional space defined by a depth axis Z indicating the depth direction of the display image displayed on the display 27.

  The display information extraction unit 16 sets the depth space as follows. First, when the current position information of the object selection device is updated by the position acquisition unit 13, the display information extraction unit 16 sets the latitude and longitude indicated by the updated current position information as the current position O in the two-dimensional space. Set. Here, the two-dimensional space is, for example, a two-dimensional virtual space defined by two orthogonal axes of an M axis corresponding to latitude and an N axis corresponding to longitude. The N-axis corresponds to the north direction detected by the direction sensor 112.

  Next, the display information extraction unit 16 sets the depth axis Z from the current position O to the direction indicated by the direction information held by the direction acquisition unit 14. If the direction information is, for example, θ1 clockwise with respect to the north direction, the depth axis Z is set at an angle θ1 with respect to the N axis. Hereinafter, the direction away from the current position O is described as the back side, and the direction approaching the current position O is described as the near side.

  Next, the display information extraction unit 16 sets two direction boundaries L1 and L2 in which the predetermined internal angle θ is equally divided by the depth axis Z and passes through the current position O. Here, as the internal angle θ, for example, an angle set in advance according to the video range of the camera 28 is employed, and for example, the horizontal angle of view of the camera 28 is employed.

  Next, the display information extraction unit 16 plots, in the depth space, a real object located in a region surrounded by the direction boundaries L1 and L2 among the real objects RO stored in the object information database 15. In this case, the display information extraction unit 16 extracts a real object located in the region surrounded by the direction boundaries L1 and L2 from the latitude and longitude of the real object stored in the object information database, and extracts each extracted real object as a depth. Plot in space.

  Note that each real object RO stored in the object information database 15 may be set in the two-dimensional space in advance, and in this case, the display information extraction unit 16 may omit the process of plotting the real object RO. it can.

  Next, the display information extraction unit 16 sets the near boundary L3 at a position separated from the current position O by a distance Zmin. Here, the near boundary L3 is a curve sandwiched between the direction boundaries L1 and L2 in the circumference having the radius Zmin centered on the current position O.

  Further, the display information extraction unit 16 sets the far boundary L4 at a position separated from the current position O by the distance Zmax. Here, the far boundary L4 is a curve sandwiched by the direction boundaries L1 and L2 in the circumference having the radius Zmax with the current position O as the center.

  On the display 27, the real object RO plotted in the display area GD surrounded by the direction boundaries L1, L2, the near boundary L3, and the far boundary L4 is displayed by the tag T1.

  FIG. 4 is a diagram illustrating an example of a display image displayed on the display 27 in the present embodiment. FIG. 4A is a display image in which a video image captured by the camera 28 and the tag T1 are superimposed. (B) shows a display image displayed on the display 27 when a desired tag is selected from the plurality of tags T1 shown in (a), and (c) shows a modification of (a). A display image is shown. FIG. 4C will be described later.

  A tag T1 shown in FIGS. 4A and 4B is a small circular image for notifying the user that there is information associated with a real object displayed behind, and is an example of an object. It corresponds to. Note that the shape of the tag T1 is not limited to a circular shape, and various shapes such as a rectangular shape and a polygonal shape can be employed.

  When any one of the tags T1 shown in FIG. 4A is selected by the user, the related information of the selected tag T1 is displayed on the display 27 as shown in FIG. 4B. The

  As shown in FIG. 3, when the tag T1 of the real object at infinity from the current position O is displayed on the display 27, the number of tags T1 displayed on the display 27 becomes enormous. In addition, since the tags T1 of real objects located far away so that the user cannot see them are also displayed, these tags T1 obstruct the display of the tag T1 that should be displayed near the user.

  Therefore, in the present embodiment, the display of the tag T1 is limited so that the tag T1 of the real object located far from the far boundary L4 with respect to the current position O is not displayed.

  Moreover, even if the tag T1 of the real object extremely close to the current position O is displayed, there is a possibility that these tags T1 occupy the display image and become an obstacle. Therefore, in the present embodiment, the display of the tag T1 is limited so that the tag T1 of the real object positioned closer to the current position O than the near boundary L3 is not displayed.

  Returning to FIG. 1, the input unit 17 acquires the coordinate data on the display image touched by the user when the operation command input notification is output by the input / state change detection unit 12. Here, two-dimensional coordinate data including vertical and horizontal coordinates of the display image is adopted as the coordinate data.

  Further, the input unit 17 determines, based on the acquired coordinate data, whether the operation command input by the user is a depth selection command for selecting a depth or a tag selection command for selecting the tag T1. To do.

  FIG. 5 shows an example of a display image according to the embodiment of the present invention. In the example of FIG. 5, the slide operation unit SP is displayed on the right side. The slide operation unit SP includes a frame WK and a slide bar BR surrounded by the frame WK. The user inputs a depth selection command by sliding the slide bar BR.

  Therefore, the input unit 17 determines that the user has input a depth selection command when the acquired coordinate data is located within the area of the slide bar BR. On the other hand, the input unit 17 determines that the user has input an object selection command when the acquired coordinate data is located within the region of any tag T1.

  In addition, even if the acquired coordinate data is not located in the area | region of which tag T1, the input part 17 will be a user, when the tag T1 is located in the fixed distance range from the position which coordinate data shows. It is determined that an object selection command has been input.

  When the input unit 17 determines that the user has input a depth selection command, the input unit 17 determines the slide bar BR from the coordinate data when the touch on the touch panel 113 is started and the coordinate data when the touch is ended. The slide amount of the slide bar BR is specified by adding the slide amount when the touch is started to the change amount of the slide specified by specifying the slide amount change amount, and the specified slide amount is set to the depth selection unit. 18 is output. On the other hand, if the input unit 17 determines that the user has input an object selection command, the input unit 17 outputs the acquired coordinate data to the object selection unit 20.

  In the example of FIG. 1, the touch panel 113 is used as an input device, but instead of this, any input device that can specify a specific position of a display image such as a mouse or an infrared pointer can be used. A device may be employed.

  Further, as an input device, a device provided separately from the object selection device, such as a remote control for remotely operating a television, may be employed.

  The depth selection unit 18 selects a depth selection position indicating a position on the depth axis Z based on a depth selection command input by the user. Specifically, the depth selection unit 18 receives the slide amount of the slide bar BR of the slide operation unit SP as a depth selection command, and changes the depth selection position in conjunction with the slide amount.

  FIG. 6 is a diagram illustrating a depth space when the slide bar BR is slid. The depth selection unit 18 sets the depth selection position Zs at a position on the depth axis Z shown in FIG. 6 according to the total length x indicating the slide amount of the slide bar BR shown in FIG. That is, when the total length x is 0, the depth selection unit 18 sets the depth selection position Zs to the position of Zmin, that is, the near boundary L3. Further, when the slide bar BR is slid upward and the total length x increases, the depth selection unit 18 moves the depth selection position Zs to the back side along the depth axis Z accordingly. Further, when the total length x of the slide bar BR reaches Xmax, the depth selection unit 18 sets the depth selection position Zs to the position of Zmax, that is, the far boundary L4.

  Further, when the slide bar BR is slid downward and the total length x decreases, the depth selection unit 18 moves the depth selection position Zs along the depth axis Z to the front side accordingly.

  Specifically, the depth selection unit 18 calculates the depth selection position Zs according to the following equation (1).

Zs = (Zmax−Zmin) * ((x / Xmax) ² ) + Zmin (1)

  As shown in Expression (1), the term (x / Xmax) is squared. Therefore, as the total length x of the slide bar BR increases, the change rate of the depth selection position Zs with respect to the change rate of the full length x increases.

  Thereby, the resolution of selection of the depth selection position Zs is higher as the total length x is shorter, and the resolution of the depth selection position Zs is lower as the total length x is longer. As a result, the user can accurately adjust the display and non-display of the tag T1 on the near side.

  It should be noted that when the position of the slide bar BR is moved up and down by the user, the depth selection unit 18 instructs the drawing unit 22 to update the display screen of the display 27 and display the slide bar BR in a slide manner accordingly.

  Further, when the fine adjustment operation unit DP for finely adjusting the total length x of the slide bar BR is operated by the user, the depth selection unit 18 slides the total length x according to the operation, and interlocks with the slide to select the depth selection position Zs. May be set.

  FIG. 7 is a diagram illustrating a display screen on which the fine adjustment operation unit DP is displayed. As shown in FIG. 7, the fine adjustment operation unit DP is displayed, for example, on the right side of the slide operation unit SP. A part of the fine adjustment operation unit DP is exposed from the surface of the display screen, and rotates in a direction parallel to the display screen. It is displayed in a display mode simulating a rotating dial.

  When the user touches the display area of the fine adjustment operation unit DP and moves the finger upward or downward, the depth selection unit 18 discretizes the rotation amount of the fine adjustment operation unit DP according to the movement amount FL1 of the finger. The total length x of the slide bar BR is slid upward or downward with a change amount Δx corresponding to the determined rotation amount, and the fine adjustment operation unit DP is rotated and displayed with the determined rotation amount.

  Here, the depth selection unit 18 determines that the change amount Δx1 of the total length x with respect to the finger movement amount FL1 when the fine adjustment operation unit DP is operated by the user is the finger movement when the user directly operates the slide bar BR. The slide bar BR is slide-displayed so as to be smaller than the change amount Δx2 of the total length x with respect to the amount FL1.

  That is, assuming that the movement amount of the finger is FL1, when the slide bar BR is directly operated, the change amount Δx1 of the total length x of the slide bar BR is, for example, FL1, but the fine adjustment operation unit DP is operated. The change amount Δx2 is, for example, α · Δx1. However, α is 0 <α <1. In the present embodiment, for example, 1/5 is adopted as α, but is not limited to this, and values such as 1/3, 1/4, 1/6, etc. may be adopted.

  The fine adjustment operation unit DP does not need to be a dial type, and may be constituted by a rotating body whose rotation amount is continuously determined according to the finger movement amount FL1. In this case, the user can adjust the depth selection position Zs more finely.

  It is not easy for a user who is unfamiliar with the operation of the touch panel 113 to directly operate the slide bar BR. Therefore, a fine adjustment operation unit DP is provided to slide the slide bar BR in conjunction with the rotation operation.

  Returning to FIG. 1, the display determination unit 19 determines whether each real object RO is located on the near side or the far side with respect to the depth selection position Zs in the depth space, and the real object located on the far side. The object RO is extracted as a real object RO to be displayed on which the tag T1 is displayed.

  Accordingly, when the slide bar BR shown in FIG. 7 is slid upward by the user, or when the slide bar BR is slid upward by rotating the fine adjustment operation unit DP upward, accordingly, The tags T1 displayed on the near side are sequentially hidden from the display, and the number of displayed tags T1 is reduced.

  On the other hand, when the slide bar BR is slid downward in the vertical direction or when the slide bar BR is slid downward by rotating the fine adjustment operation unit DP downward, the back The number of tags T1 displayed from the side toward the front side is sequentially increased.

  As a result, the tag T1 that has been disturbed by the tag T1 displayed in front and the tag T1 that has not been exposed so much is exposed greatly, and the user can easily perform an operation of selecting these tags T1. be able to.

  Here, the display determination unit 19 displays the tag T1 of the real object RO located in front of the depth selection position Zs shown in FIG. 6 and located in the area surrounded by the direction boundaries L1 and L2 in a translucent manner. In this way, the drawing unit 22 may draw the image. In this case, the drawing unit 22 may synthesize the tag T1 and the video data captured by the camera 28 with a predetermined transmittance using a technique such as α blending.

  Returning to FIG. 1, when the object selection unit 20 determines that the object selection command is input from the input unit 17 and the coordinate data of the touch position is output, the tag T1 selected by the user from the display target tags T1. Is identified.

  When the touch panel 113 is used as an input device, the touch position recognized by the user may be shifted from the touch position recognized by the apparatus. Therefore, when a plurality of tags T1 are displayed in the vicinity of the touch position, there is a possibility that a tag T1 different from the tag T1 that the user tried to select is selected.

  In the object selection device according to the present embodiment, since the user can hide the tag T1 displayed in front of the tag T1 to be selected, the tag T1 to be selected by the user is located around the touch position. There is a high possibility of being displayed in the forefront among the tags T1 displayed in (1).

  Therefore, the object selection unit 20 specifies the tag T1 displayed in the forefront within a certain distance range from the touch position as the tag T1 selected by the user.

  FIG. 8A is a diagram showing the touch position of the user, and FIG. 8B is a screen diagram when a plurality of related information is displayed at the same time. In FIG. 8A, PQx indicates a touch position touched by the user. In this case, the object selection unit 20 specifies the tag T1_1 located closest to the tag T1_1, T1_2, T1_3, and T1_4 located within a certain distance d from the touch position PQx as the tag selected by the user. . Here, the object selection unit 20 may specify the tag T1 having the shortest distance between the position in the depth space of the real object RO corresponding to the tags T1_1 to T1_4 and the current position O as the nearest tag T1.

  As described above, the object selection unit 20 basically identifies the tag T1 that is the foremost tag T1 within the fixed distance d from the touch position as the tag T1 selected by the user. When a plurality of tags T1 are displayed in the vicinity of the tag T1 to be tried, the user may not know which position can be touched to select the desired tag T1.

  Therefore, the object selection unit 20 sets the small area RD at the position of the depth space corresponding to the touch position, and causes the display 27 to display related information on all the real objects RO located in the set small area RD.

  FIG. 9 is a diagram illustrating a small region RD that the object selection unit 20 sets in the depth space. First, the object selection unit 20 specifies the position in the depth space of the real object RO corresponding to the tag T1 determined to be positioned closest to the front. In FIG. 9, it is assumed that the real object RO_f is the real object RO. Next, the object selection unit 20 obtains an internal division ratio (m: n) in which the touch position PQx internally divides the lower side of the display image from the left end in FIG. Next, the object selection unit 20 sets, as an equidistant curve Lx, a circumference having a radius of the distance between the real object RO_f and the current position O around the current position O in the depth space illustrated in FIG.

  Next, a point that internally divides the equidistant curve Lx into m: n with respect to the direction boundary Z1 is obtained as a position Px in the depth space corresponding to the touch position PQx.

  Next, a straight line L6 passing from the current position O to the position Px is set. Next, two straight lines L7 and L8 passing through the current position O are set so that the predetermined angle θ3 is equally divided by the straight line L6. Next, the distance between the position Px shifted by Δz along the straight line L6 and the current position O is set as a radius, and the circumference centered on the current position O is set as an equidistant curve L9. As described above, the area surrounded by the equidistant curves Lx and L9 and the straight lines L7 and L8 is set as the small area RD.

  As the angles θ3 and Δz, for example, values determined in advance based on a shift between an assumed touch position recognized by the user and a touch position recognized by the touch panel 113 can be employed.

  Then, when the object selection unit 20 notifies the related information acquisition unit 21 of the real object RO included in the set small region RD, the related information acquisition unit 21 displays the related information of the notified real object RO in the object information database 15. And the drawing unit 22 draws the extracted related information.

  As a result, a display image as shown in FIG. 8B is displayed on the display 27. In the example of FIG. 8B, since the four real objects RO are included in the small area RD, the related information of the four real objects RO is displayed.

  Here, in FIG. 8B, only some information such as the name of the real object RO among the related information stored in the object information database 15 is displayed as the related information to be displayed. Then, when the touch panel 113 is touched by the user and any one real object RO is selected, detailed related information of the real object RO may be displayed. As a result, it is possible to save display space when displaying a plurality of related information at a time, and to display more related information. If the related information to be displayed at one time does not fit in the display area of the display 27, the related information may be scroll-displayed.

  Returning to FIG. 1, the related information acquisition unit 21 extracts the related information of the tag T <b> 1 determined to be selected by the user by the object selection unit 20 from the object information database 15 and causes the drawing unit 22 to display the extracted related information. . As described above, when a plurality of real objects RO are included in the small area RD, the related information of the plurality of real objects RO is extracted from the object information database 15, and the extracted plurality of related information is displayed. It is displayed on the drawing unit 22.

  The drawing unit 22 determines the display position of the display target real object RO extracted by the display determination unit 19 in the display image, and draws the tag T1 at the determined display position.

  Here, the drawing unit 22 may determine the display position of the tag T1 from the positional relationship between the current position O and the real object RO to be displayed in the depth space. Specifically, the display position may be determined as follows.

  First, as shown in FIG. 6, a curve on the circumference passing through the real object RO_1 with the current position O as the center and surrounded by the direction boundaries L1 and L2 is set as an equidistant curve L5. Next, a distance Zo between the current position O and the real object RO_1 is obtained.

  Next, as shown in FIG. 7, a rectangular area SQ1 corresponding to the distance Zo is set as a display image. Here, the center of the rectangular area SQ1 is located at the center OG of the display image, for example, and has a shape similar to the shape of the display image. Note that the size of the rectangular area SQ1 has a size that is reduced at a predetermined scale according to the distance Zo. Here, the relationship between the scale ratio and the distance Zo is such that the scale ratio increases as the distance Zo increases, the scale ratio decreases as the distance Zo decreases, and becomes 1 when the distance Zo is zero. Have.

  Next, an internal ratio at which the real object RO_1 shown in FIG. 6 internally divides the equidistant curve L5 is obtained. Here, it is assumed that the real object RO_1 internally divides the equidistant curve L5 into m: n with the direction boundary L1 as a reference.

  Next, a point Q1 that internally divides the lower side of the display image shown in FIG. 7 into m: n is obtained, and the horizontal coordinate in the display image of the obtained point Q1 is set to the horizontal position of the display position P1 of the tag T1 of the real object RO_1. Obtained as the coordinate H1 of the direction.

  Next, when the height of the real object RO_1 is stored in the object information database 15, the height h is obtained by scaling the height h at a scale ratio corresponding to the distance Zo, and the lower side of the rectangular area SQ1. The vertical coordinate of the display image that is separated by a height h ′ from the vertical direction is obtained as the vertical coordinate V1 of the display position P1. When the height of the real object RO_1 is not stored, the tag T1 may be displayed at an appropriate position on the straight line passing through the coordinate H1.

  Next, the area of the tag T1 is reduced at a reduction ratio according to the distance Zo, and the reduced tag T1 is displayed at the display position P1. The depth selection unit 18 performs the above processing for each real object RO for which the tag T1 is to be displayed, and determines the display position.

  Returning to FIG. 1, the drawing unit 22 draws the slide operation unit SP and the fine adjustment operation unit DP in the graphics frame memory 23 in accordance with the drawing request from the depth selection unit 18. In addition, the drawing unit 22 draws related information in the graphics frame memory 23 in accordance with a drawing request from the related information acquisition unit 21.

  The graphics frame memory 23 is a memory that holds image data drawn by the drawing unit 22. The video input unit 24 acquires real-world video data captured at a predetermined frame rate by the camera 28 and sequentially writes it in the video frame memory 25. The video frame memory 25 is a memory that temporarily holds video data output from the video input unit 24 at a predetermined frame rate.

  The composite display unit 26 superimposes the video data held in the video frame memory 25 and the image data held in the graphics frame memory 23 to generate a display image that is actually displayed on the display 27. Here, the composite display unit 26 superimposes the image data held in the graphics frame memory 23 before the video data held in the video frame memory 25. As a result, the tag T1, the slide operation unit SP, and the fine adjustment operation unit DP are displayed in front of the real-world image. The display 27 is composed of, for example, a liquid crystal panel or an organic EL panel with a touch panel 113 attached to the surface, and displays a display image synthesized by the synthesis display unit 26. The camera 28 acquires real-world video data at a predetermined frame rate and outputs it to the video input unit 24.

  FIG. 10 is a flowchart showing processing until the object selection device according to the present embodiment displays the tag T1. First, the input / state change detection unit 12 detects an operation command input by the user or a state change of the object selection device (step S1). Here, the input of the operation command is that the user touches the touch panel 113, and the state change includes a change in the position of the object selection device and a change in the direction.

  Next, when the input / state change detection unit 12 detects a change in the position of the object selection device (step S2: YES), the position acquisition unit 13 acquires position information from the GPS sensor 111 (step S3).

  On the other hand, when the input / state change detection unit 12 detects a change in the direction of the object selection device (step S2: NO and step S4: YES), the direction acquisition unit 14 acquires direction information from the direction sensor 112 (step S5). ).

  Next, the display information extraction unit 16 generates a depth space using the latest position information and direction information of the object selection device, and sets the real object RO located in the display area GD as the real object RO to be displayed. Extract (step S6).

  On the other hand, when the input unit 17 determines that a depth selection command has been input by the user (step S4: NO and step S7: YES), the depth selection unit 18 determines from the total length x of the slide bar BR operated by the user. A depth selection position Zs is set (step S8).

  Next, the display determination unit 19 selects the real object RO located behind the depth selection position Zs set by the depth selection unit 18 from the real objects RO to be displayed extracted by the display information extraction unit 16. Is extracted as a real object RO to be displayed (step S9).

  Next, the drawing unit 22 determines the display position of the tag T1 from the positional relationship between the current position O and the real object RO in the depth space (step S10).

  Next, the drawing unit 22 draws the tag T1 of the real object RO to be displayed at the determined display position (step S11). Next, the composite display unit 26 combines the image data and the video data so that the image data held in the graphics frame memory 23 is superimposed on the upper side of the video data held in the video frame memory 25. A display image is generated and displayed on the display 27 (step S12).

  FIG. 11 is a flowchart showing processing until the related information corresponding to the tag T1 selected by the user is displayed on the display 27.

  First, the input / state change detection unit 12 detects that an operation command has been input from the user (step S21). Next, when the input unit 17 determines that the operation command from the user is a tag selection command (step S22: YES), the object selection unit 20 determines the distance d from the touch position PQx as shown in FIG. The tag T1_1 located in the forefront is extracted from the inside tags (step S23).

  On the other hand, if the input unit 17 determines that the operation command from the user is not a tag selection command (step S22: NO), the process returns to step S21.

  Next, as illustrated in FIG. 9, the object selection unit 20 sets the small area RD at the position in the depth space of the real object RO_f corresponding to the tag T1_1, and sets the real object RO included in the set small area RD. Extract (step S24).

  Next, the related information acquisition unit 21 acquires related information of the extracted real object RO from the object information database 15 (step S25). Next, the drawing unit 22 draws the related information acquired by the related information acquisition unit 21 in the graphics frame memory 23 (step S26).

  At this time, when the object selection unit 20 extracts a plurality of real objects RO, related information of the plurality of real objects RO is drawn as shown in FIG.

  Next, the composite display unit 26 combines the image data and the video data so that the image data held in the graphics frame memory 23 is displayed above the video data held in the video frame memory 25, and the display 27 (step S27).

  When the object selection unit 20 extracts a plurality of real objects RO, the related information of only one real object RO closest to the depth selection position Zs set by the depth selection unit 18 may be displayed on the display 27.

  Further, an image for selecting one related information from the plurality of related information shown in FIG. 8B is displayed on the display 27, and one related information selected by the user is displayed on the display 27. May be.

  When displaying the related information, the composite display unit 26 generates a display image from only the image data held in the graphics frame memory 23 without combining the video data held in the video frame memory 25, and It may be displayed on the display 27.

  In the above description, the user selects the depth selection position Zs using the slide bar BR as shown in FIG. 7, but the present invention is not limited to this, and the selection operation unit KP shown in FIG. 12 is used. The user may be allowed to select the depth selection position Zs.

  12A and 12B are diagrams showing display images on which the selection operation unit KP is displayed. When the selection operation unit KP is employed, the depth space is divided into a plurality of depth regions by dividing the depth axis Z. FIG. 13 is a diagram illustrating a depth space when the selection operation unit KP of FIG. 12 is employed.

  As shown in FIG. 13, the depth space is partitioned into seven depth regions OD1 to OD7 by partitioning the depth axis Z. Specifically, in the depth space, seven depth regions OD1 to OD7 are set by dividing the display region GD into seven regions concentrically around the current position O. Here, the respective widths of the depth regions OD1 to OD7 may be set so as to decrease as the distance from the current position O increases, or may be the same.

  As shown in FIG. 12A, the selection operation unit KP includes a plurality of selection areas DD1 to DD7 that are associated with the depth areas OD1 to OD7 and arranged in different colors. Here, since there are seven depth regions OD1 to OD7, there are seven selection regions DD1 to DD7.

  The user touches the touch panel 113 to select any one of the selection areas DD1 to DD7 and input a depth operation command. Hereinafter, when the depth regions OD1 to OD7 are not distinguished, they are described as a depth region OD, and when the selection regions DD1 to DD7 are not distinguished, they are described as a selection region DD. Further, the number of depth regions OD and the number of selection regions DD are not limited to seven, and an appropriate number of two or more and six or less, or eight or more may be employed.

  The drawing unit 22 draws the tag T1 of each real object RO with the same color as the color of the selection area DD associated with the depth area OD to which the real object RO belongs.

  For example, if the first to seventh colors are assigned to the selection areas DD1 to DD7, the drawing unit 22 assigns the first color to the tag T1 of the real object RO located in the depth area OD1. Then, the tag T1 of the real object RO located in the depth region OD2 is given a color such that the second color is given to the tag T1.

  When the selection area DD3 is touched by the user, for example, the depth selection unit 18 selects the position on the depth axis Z of the front boundary of the depth area OD3 associated with the selection area DD3 as the depth selection position Zs. To do.

  Then, the display determination unit 19 extracts the real object RO located behind the depth selection position Zs as the real object RO to be displayed, and causes the drawing unit 22 to draw the tag T1 of the extracted real object RO. Therefore, when the selection area DD3 is touched by the user, in FIG. 12A, the tag T1 displayed in the first and second colors is hidden and the tag displayed in the third to seventh colors. Only T1 is displayed.

  Note that, as the first color to the seventh color, it is preferable to employ a gradation color in which the color gradually changes from the first color toward the seventh color.

  In the above description, a mode has been adopted in which the tag T1 is superimposed on the real object RO included in the video data captured by the camera 28, but the present invention is not limited to this. For example, the present invention may be applied to a graphical user interface of a computer or AV device that three-dimensionally displays icons and folders.

  In this case, if the object composed of icons and folders used in the above description is handled in the same manner as the real object RO, the object OB is displayed three-dimensionally instead of the tag T1 as shown in FIG. Good. In the example of FIG. 4C, it can be seen that the area of the object OB is gradually reduced from the object OB on the near side toward the object OB on the back side, and the object OB is displayed three-dimensionally.

  In this case, when the position of each object OB is plotted in the depth space, and the depth selection position Zs is set according to the slide amount of the slide bar BR, the display determination unit 19 is further on the back side than the depth selection position Zs. This object OB may be extracted as a display target object OB and drawn by the drawing unit 22.

  Also, as shown in FIG. 12B, each object OB may be displayed using a color corresponding to the depth area OD to which each object OB belongs, as in FIG. In this case, when any one of the selection areas DD in the selection operation unit KP is touched, the position on the depth axis Z of the front boundary of the depth area OD corresponding to the touched selection area DD is the depth selection position. The display determination unit 19 is set as Zs, and the object OB on the back side from the depth selection position Zs may be extracted as the display target object OB and drawn by the drawing unit 22.

  Further, the slide bar BR may be included in the depth selection operation unit KP shown in FIGS. In this case, when the user positions the tip of the slide bar BR in the desired selection area DD, the tag T1 or the object OB on the back side of the depth area OD corresponding to the selection area DD is drawn on the display 27.

  Moreover, although the example which comprises an object selection apparatus with a smart phone was shown in the said description, it is not limited to this, You may apply to a head mounted display.

  In the above description, the slide operation unit SP, the selection operation unit KP, and the fine adjustment operation unit DP are displayed on the display 27. However, the present invention is not limited to this, and may be configured as a physical input device. Good.

  In the above description, the slide operation unit SP, the selection operation unit KP, and the fine adjustment operation unit DP are displayed on the display 27. However, the present invention is not limited to this, and the object selection device is, for example, an acceleration sensor. In the case of a mobile terminal having a function of detecting the inclination of the device itself, the depth selection command may be issued based on the direction and amount of change in the inclination of the terminal. In this case, for example, tilting the mobile terminal toward or away from the front corresponds to sliding the slide bar BR of the slide operation unit SP up and down, and the amount of change in tilt corresponds to the slide amount of the slide bar BR.
